Water leak outside property

Ben-gee · Jan 10, 2024

The first one is a size specific slip coupling only for mdpe pipe.
The more expensive one is designed to deal with different pipes eg galvanised or whatever you might come across with that diameter.

In your case you only need the mdpe plasson coupler.

Right had not noticed the szing of the fittings. Thanks.

Just received the squeeze off tool. Not sure why I thought it would be much bigger than it is, quite dinky. All I need to do now
is get bup the courage to go outside and dig a few holes in this damned cold weather. Tomorrow sounds a good idea.

Right an update. Dug out a few holes and found a T piece outside where the water enters the property. I knew there had to be a T somewhere as supply also feeds an outbuilding. Now the pipe is black 3/4inch MDPE and the T piece is an equal brass
compression fitting. As far as I can see 3/4in brass compression are classed as Irish pipe fittings, must be something to do with the Guiness.
So my intention is to remove the T piece and use a stop end at the incoming supply end of the T. That will let me determine whether the leak is between the T and the meter or not. I thought this might be less harmful to the pipe than using the squeeze tool I have just bought. Any thoughts?

So bit the bullet and used the squeeze off tool. Was hesitant as to if it would damage the pipe, I need not have worried. Warmed the pipe up a bit with a heat gun and it shut the water flow off a treat. Took it off and put back on at 90deg to previous position to get rig of the slight kink in the pipe. Is now fully round. Least it has shown me which leg the leak is on. Luckily the one going across a lawn, about 10m, and not from the meter to the house about 35 m. So only have to mess around doing holes on 10m worth.

Sounds like a good result.

Just for your information- the black mdpe you have found is almost certainly alkathene and not mdpe.
Bd warned that this pipe is more inclined to become brittle with age, I would not use d squeeze off tool on it. Also if at all practical I would replace it with blue mdpe whilst you are mucking around. Note it is often easier to run a new supply by a different route and simply disconnect the old one and leave it in situ - but this will depend on the circumstances of your actual installation.

MDPE HDPE whats in a name.

Too many other things to be getting on with so no way will I replace the black with blue would be over 40m needing replacing.
The black seemed to compress yesterday very nicely and resumed its circular shape. All I want is to find the leak sort it and fill in all the holes.

Diesel Petrol what’s in a name.

Try putting the wrong one in your car and you’ll find out.

Finally traced leak with aid of a CAT4 cable tracer and genny. Problem was with fastening ring on a Philmac universal transition joiner. The ring had split for around 50% of the circumference.
Attached is a pic of current state. Original feed from meter now terminated with a stop end on a JG 3/4 in LDPE to 25mm adaptor.
I intend doing away with the boilerhouse feed and just running a supply to the garage for an outside tap. Now a slight problem is the garage pipe is
20mm MDPE and the spigot on the JG fitting is 25mm. Plus I now am about half a meter short of pipe. Now I know I can buy some 20mm pipe, a 25mm to 20mm adapter and a 20mm elbow. I just wondered am I missing anything obvious to do the job except from how I am stating here?
